Slow Cooker Creamy Mushroom Potatoes

Description

These Slow Cooker Creamy Mushroom Potatoes are an easy, comforting side dish made with tender sliced potatoes slowly cooked in a rich, savory mushroom cream sauce. The potatoes absorb the flavors of mushrooms, garlic, onion, herbs, and creamy sauce as they cook, becoming wonderfully soft while maintaining their shape. A little sour cream and Parmesan add extra richness, while black pepper and thyme balance the creamy flavors. Everything cooks right in the crockpot, making this recipe especially convenient for busy weeknights, Sunday dinners, holidays, potlucks, or family gatherings. Serve these creamy potatoes alongside roasted chicken, pork chops, steak, meatloaf, or vegetables for a satisfying homemade meal.

Ingredients For the Potatoes

• 3 lbs Yukon Gold or russet potatoes
• 1 tbsp butter, for greasing the slow cooker
• 1 small yellow onion, finely diced
• 2 garlic cloves, minced
• 8 oz mushrooms, finely chopped
• ½ tsp salt
• ½ tsp freshly ground black pepper
• ½ tsp dried thyme
• ½ tsp garlic powder
• ½ tsp onion powder

For the Creamy Mushroom Sauce

• 2 cans (10.5 oz each) condensed cream of mushroom soup
• ¾ cup whole milk
• ½ cup sour cream
• ½ cup grated Parmesan cheese
• 1 tbsp Worcestershire sauce
• ½ tsp smoked paprika, optional
• 2 tbsp melted butter

Optional Garnish

• Fresh parsley, chopped
• Fresh thyme
• Extra Parmesan cheese
• Freshly ground black pepper

Step-by-Step Instructions

1. Lightly grease the inside of a 5–6 quart slow cooker with butter.
2. Wash and scrub the potatoes thoroughly. Peel them if desired, although Yukon Gold potatoes can be prepared with their skins intact.
3. Slice the potatoes into approximately ¼-inch-thick rounds. Keeping the slices similar in thickness helps them cook evenly.
4. Place the sliced potatoes in a large bowl and set aside while preparing the mushroom sauce.
5. In another mixing bowl, combine the condensed cream of mushroom soup, whole milk, sour cream, Parmesan cheese, Worcestershire sauce, melted butter, garlic powder, onion powder, thyme, smoked paprika, salt, and black pepper.
6. Stir thoroughly until the mixture is smooth and creamy.
7. Add the finely chopped mushrooms, diced onion, and minced garlic to the sauce.
8. Stir again until the mushrooms and onions are evenly distributed throughout the creamy mixture.
9. Arrange approximately one-third of the sliced potatoes across the bottom of the prepared slow cooker.
10. Spoon approximately one-third of the creamy mushroom sauce over the potatoes and gently spread it across the surface.
11. Add another layer of sliced potatoes followed by another portion of mushroom sauce.
12. Repeat with the remaining potatoes and sauce, making sure the top layer is generously covered.
13. Cover the slow cooker securely with the lid.
14. Cook on LOW for approximately 5–6 hours or HIGH for approximately 3–4 hours.
15. Avoid opening the lid repeatedly during cooking because releasing steam can increase the cooking time.
16. Begin checking the potatoes toward the end of the recommended cooking time. Insert a fork or small knife into the center slices. They should be completely tender.
17. Once tender, gently stir the potatoes from the sides toward the center, taking care not to break them apart excessively.
18. If the sauce seems too thick, stir in a small splash of warm milk.
19. If the sauce seems thinner than desired, leave the slow cooker uncovered on HIGH for approximately 15–20 minutes to allow some moisture to evaporate.
20. Taste and adjust the salt and black pepper as necessary.
21. Turn off the slow cooker and allow the potatoes to rest for approximately 10 minutes. The creamy mushroom sauce will continue to thicken as it stands.
22. Garnish with fresh parsley, thyme, additional Parmesan, and freshly ground black pepper.
23. Serve warm directly from the crockpot.

Tips

• Slice the potatoes evenly. A mandoline slicer works particularly well for producing consistent slices.
• Yukon Gold potatoes have a naturally creamy, buttery texture and hold their shape nicely during slow cooking.
• Don’t make the slices too thick or the potatoes may require considerably more cooking time.
• Fresh mushrooms add extra texture and mushroom flavor beyond the condensed soup.
• For an even richer version, replace part of the milk with heavy cream.
• Don’t add too much salt initially because condensed soup and Parmesan can already contain substantial sodium.
• For extra cheesy potatoes, sprinkle shredded cheddar, mozzarella, or Gruyère over the top during the final 20–30 minutes.

Notes

These potatoes are best served warm while the sauce is creamy and silky. If preparing them for a gathering, they can be kept on the WARM setting briefly after cooking. Stir gently before serving. Refrigerate leftovers promptly in an airtight container for up to 3–4 days. Reheat gently in the microwave or oven, adding a splash of milk if the sauce has become too thick.

Q&A

Can I use russet potatoes?
Yes. Russets work well, although they tend to soften and break down more than Yukon Gold potatoes.
Can I add cheese?
Absolutely. Cheddar, Gruyère, mozzarella, or Monterey Jack can be added for an extra-cheesy version.
Do I have to peel the potatoes?
No. Thin-skinned potatoes can be thoroughly scrubbed and cooked with their skins on.
Can I add meat to make it a complete meal?
Yes. Fully cooked diced ham or browned sausage can be layered with the potatoes. Ensure any meat used is properly cooked and heated through before serving.
Why are my potatoes still firm?
Slow cookers vary in temperature, and thicker potato slices require longer cooking. Continue cooking until the center slices are easily pierced with a fork.
